• Trump says his second inauguration will be held in the Capitol rotunda.
• The ceremony is usually outside, but is being held indoors due to freezing temperatures.
• It's the first time this has happened since Ronald Reagan's 2nd inauguration in 1985.

President-elect Donald Trump announced on Friday that his second inauguration will be moved indoors due to expected freezing temperatures.

"The weather forecast for Washington, D.C., with the windchill factor, could take temperatures into severe record lows," Trump wrote in a Truth Social post. "There is an Arctic blast sweeping the Country. I don't want to see people hurt, or injured, in any way."

Presidential swearing-in ceremonies are typically held outdoors on a platform in front of the United States Capitol, allowing crowds to view the event from the National Mall. However, Trump said on Friday that the ceremonies would instead take place inside the Capitol Rotunda.

It's not the first time an American president has been sworn in beneath the rotunda.

President Ronald Reagan was also sworn in under the Capitol rotunda in 1985, when he was inaugurated for his second term, also after freezing temperatures prompted organizers to make a last-minute change of plans.

Trump referenced Reagan's 1985 inauguration in his Friday Truth Social post, adding that the "various Dignitaries and Guests will be brought into the Capitol." Several business and tech CEOs are expected to be in attendance.

The president-elect also said that the presidential parade would be moved to Capital One arena, where a live viewing will also take place. Trump said he would travel to the arena after he's sworn in.
